The Olympics of Comedy will be covered in about the same style as the Olympic Games when Bob Newhart hosts Showtime's 90-minute extravaganza, "Just For Laughs: The Montreal International Comedy Festival," Saturday at 10.

The festival began eight years ago and now draws about 250 acts from all around the world. Attendance seems to double each year; last year, there were 450,000 spectators.

One feature is the two-year-old Street Festival, designed to showcase the European tradition of street performers as an art form.

"The festival is a beautiful mixture of established American, Canadian and British acts combined with raw talent from the world over," said festival vice president Andy Nulman.

"Up-and-comers from every civilized country, and some not so civilized, enjoy exposure in front of the major industry executives and decision makers."

Among those scheduled to perform on the televised segment are Martin Mull, "Weird Al" Yankovic, Dave Thomas, Andre-Philippe Gagnon, Dana Gould, Jeremy Hardy and Norbert Sinz. Encores: July 27 and 30.

Sunday on Showtime at 9. Ally Sheedy, Lauren Hutton and Michael O'Keefe star in an original psychological thriller, "Fear." The movie sets a psychic, Sheedy, against a killer whose physic powers rival her own. Encores: July 23, 27, 31.

Monday on HBO at 10. "Guns: A Day in the Death of America: America Undercover" is a chilling account of all gun-related deaths on a randomly selected day -- July, 16, 1989. This one-hour documentary records 61 deaths that day, exactly one year ago. Additional playdates: July 19, 22, 25, 27 and 31.

Lifetime and Warner Bros. have signed a deal for 20 movies that will bypass the syndication market and make their basic cable premieres on Lifetime. The package includes such high-profile titles as "The Accidental Tourist," "Dangerous Liaisons," "Tequila Sunrise," "The Color Purple," "Empire of the Sun," "After Hours," "Clean and Sober" and "A Cry in the Dark." Playdates are pending.

At USA, 20 additional episodes of "The Hitchhiker" begin shooting Monday in Toronto and Paris. The new episodes of the show, which has won eight Ace Awards, will air beginning Sept. 21.
